Also, a simple contactor that cuts out less essential appliance, like heating, when a short period operation essential appliance cuts in.

@barryjdwyer Yep Current sensing relays that clip into the DIN rail in the main panel. Set the current switching on the front of the relay. All neat inside the panel. You can buy induction hobs that run on a 13A plug, or a 16A hard wired circuit. A 16A current sensing relay on say a few bedroom heaters will cut them out when the hob is on when drawing more than say 4 amps. Keeps the current draw within the main fuse limit.

The maximum amperage that can run through a 3-pin standard British plug is 13A - regulated by the in-plug fuse with only 13A max fuse value available. Any higher than 13A then the appliance has to be hard wired in. That delivers a max of 3,000 watts (3kW). The same amperage on 120v (USA) delivers approx half the power. The UK/EU system delivers twice as much power. In the USA they run 240v into homes, but split it for 120v and 240v appliances - different plugs. To the rest of the world that is crazy for a domestic home. They need to go over to all 240v in homes, dropping the high current (amps) 110v, and adopt the British 3-pin plug, as it is the best, and safest, by far (do not reinvent the wheel). Then USA 100A electrical supplies run in to homes can cope with most appliance in a home. By the way, EV chargers sense the current then automatically reduce current draw when approaching the max limit of supply.

@RichardBorn-ke2ui You are right on 6kW EV chargers over larger kW versions. 7.2kW usually in the UK. Your knowledge of electrical systems, never mind the ability in assessing them, is slim to say the least. It is well recognised that the British 3-pin G Type plug/socket is the best in the world by a mile. I doubt you have the ability to analyse, as no one would ever put the terrifying toy like US plug as being superior, or equal, to the British plug. Then...running two voltages into a home? Yikes! Also, earth leakage safety devices are mandatory in British main panels, reducing serve electric shocks. You are in California? Enjoy the brownouts and blackouts. I hope you are happy with third world grid and electrical systems.
